ABSTRACT:
An EMI/RFI shielded printed circuit board housing of compact design suitable for computer system products (such as, e.g., bridges and repeaters) permits such products to be used on office work surfaces or in a wall-mounted, high density storage system within an office environment. The housing has a five-sided printed-circuit-board container with a back wall defining at least on window for exposing an electrical connector that requires access from the exterior of the container, a removable front cover, a removable trough-shaped rear cover for covering the container back wall and protecting the exposed connector located thereat. The back wall is equipped with support features for permitting the housing to be supported in the high density storage system during use. The container and front cover have a plurality of interior surfaces coated with an EMI/RFI shielding material. In other aspects of the invention, the housing has printed-circuit-board-support features for precisely positioning and supporting the printed-circuit-board within the housing in such a way as to avoid contact between the printed circuit board circuitry and the EMI/RFI-shielding material. In addition, the housing has a connector-access button defining a recessed interior volume into which extends a male electrical connector mounted on the printed circuit board.
